## Which one, for what

### Google Drive API + MCP (A)

Good for: Agents working on files that people already keep in Drive, inside a Workspace organisation with admin controls.

Ahead on:
- Reliability, 90 against 64
- Security & auth, 91 against 73
- Payments & pricing, 35 against 20
- Maintenance & community, 85 against 75

Also in its favour:
- Agent-ready, a grade of BB or better
- No incidents deducted, where OneDrive and SharePoint files (Microsoft Graph) loses 4 points for them

Watch for: OAuth consent, scope verification and a Cloud project before an agent can list a folder

### OneDrive and SharePoint files (Microsoft Graph) (B)

Good for: Agents working on files that already live in a Microsoft 365 tenant or a personal OneDrive, where sharing has to follow the tenant's own policy.

Ahead on:
- Schema & documentation, 89 against 83

Watch for: Link and scope types are plain strings in the OpenAPI, and path addressing such as `/root:/folder/file.txt:` is absent from it

## Verdicts

**Google Drive API + MCP.** No charge for API calls within quota, counted in quota units per minute per project and per user. OAuth consent, scope verification and a Cloud project before an agent can list a folder.

**OneDrive and SharePoint files (Microsoft Graph).** One REST surface covers personal OneDrive, work OneDrive and SharePoint libraries, with resumable uploads, sharing links that take an expiry date and per-file Selected permissions. The status page needs JavaScript, an app must be registered and consented to by a person, and the JavaScript client on npm lacks a token-leak fix merged in June 2026.

## Before you call either

### Google Drive API + MCP

1. Ask for drive.file rather than drive; it needs no verification and covers files the app created or the user picked
2. Use uploadType=resumable for anything over 5 MB and send chunks in multiples of 256 KB
3. For a link that expires, share to a user or group with expirationTime; a type=anyone permission can't expire, so delete it yourself
4. Pass fields= on files.list and files.get to cut the response, and page with pageToken
5. Back off exponentially on 429 rateLimitExceeded and 403 userRateLimitExceeded; 403 storageQuotaExceeded won't clear by retrying

### OneDrive and SharePoint files (Microsoft Graph)

1. Use PUT `/content` only up to 250 MB. Above 10 MiB Microsoft advises `createUploadSession`, with fragments in multiples of 320 KiB and under 60 MiB each
2. Send the bearer token on the `createUploadSession` POST only. The PUT calls to `uploadUrl` can return 401 if an `Authorization` header is included
3. Set `expirationDateTime` and `scope` on `createLink`. Without a scope the tenant's default link type is created, which may be wider than intended
4. Follow the 302 from GET `/content` straight away. Pre-authenticated download URLs can expire within minutes and need no `Authorization` header
5. Wait for `Retry-After` on 429 and 503. Throttled requests still count against the limits, and continued overuse can get the app blocked
